Manganese

Also known as: Manganese Gluconate, Manganese Chelate, Manganese Sulfate, Manganese Amino Acid Chelate

MineralsTabletNatural Source

Manganese is a trace mineral essential for bone formation, wound healing, and antioxidant defense. It serves as a cofactor for numerous enzymes involved in energy metabolism, immune function, and connective tissue synthesis. Manganese is critical for cartilage and bone health.

Benefits

Essential for bone health and skeletal development. Supports wound healing and tissue repair. Acts as an antioxidant protecting cells from damage. Supports joint health and cartilage formation. Important for proper immune function. Supports brain health and cognition. May help regulate blood sugar levels.

Recommended Dosage

AI: 2.3 mg/day for men, 1.8 mg/day for women. Common supplement doses: 5–10 mg daily. Upper limit: 11 mg/day for adults. Well-absorbed with food. Chelated forms have better bioavailability than inorganic manganese. Take with meals containing healthy fats.

Food Sources

Tea (black and green), whole grains, oats, brown rice, legumes (chickpeas, lentils, beans), nuts (almonds, walnuts, hazelnuts), seeds (pumpkin, sunflower), spinach, pineapple, cloves, cinnamon.

Side Effects

Well-tolerated at recommended doses. High intakes may cause: tremors, headache, mood changes, hallucinations (manganism — occupational hazard). Excess may cause: fatigue, weakness, joint pain. Neurotoxicity possible with very high supplementation.

Interactions

May reduce absorption of antibiotics (tetracyclines, fluoroquinolones) — separate by 2–4 hours. Iron, calcium, and magnesium supplementation may interfere with absorption. Antacids reduce manganese absorption.

Warnings

Those with liver disease should use caution and monitor levels. High supplemental doses not recommended without medical supervision. Workers exposed to manganese dust should avoid supplementation. Pregnant women should not exceed AI. Those with Parkinson's disease should avoid high doses.

Deficiency Symptoms

Poor bone health and weakened skeletal development. Impaired wound healing. Joint pain and swelling. Skin rashes and dermatitis. Hair loss and brittle nails. Mood disturbances and confusion.
